OpenTreeMap is software for collaborative, geography-enabled urban tree inventory. The software enables the public, organizations, and governments to collaboratively contribute to an interactive and dynamic map of a community’s tree population. Users can search for trees, add trees to the system, edit existing tree information, or upload tree photos. The system automatically calculates a tree's ecosystem benefits based on its species and diameter. OpenTreeMap can be used in a single municipality or to cover a broader geographic region with many communities, anywhere in the world. This software also exists as a subscription-based system.

The Linux-Ecology-HOWTO discusses ways to make
computers less harmful to our environment and to
solve some ecological issues. It explains how to
use Linux to save power and consumables like paper
and ink. Since it does not require big hardware,
Linux may be used with old computers to make their
life cycle longer. Games may be used in
environmental education and software is available
to simulate ecological processes.
